Electric dipole oscillation in solids characterized by Fourier transform extreme ultraviolet attosecond spectroscopy

We characterized electronic dipole oscillations in chromium doped sapphire (Cr:Al2O3) using Fourier transform extreme ultraviolet attosecond spectroscopy (FTXUV) combined with an isolated attosecond pulse, which reveals the electric band-structure and dephasing process in solids

Multi-petahertz electron interference in Cr:Al2O3 solid-state material

Signal processing in electronic devices is in the THz regime. Here the authors measure NIR lightwave-field-induced multiple dipole oscillations in Cr:Al2O3 in the time domain reaching PHz scale by using an isolated attosecond pulse and this method shows potential for higher speed signal processing
